Is it COVID-19? Flu? At-home rapid tests could help you and your doctor decide on a treatment plan
At-home rapid tests for COVID-19 and influenza are becoming available, allowing simultaneous diagnosis, which aids timely and effective treatment and improves patient outcomes.

A scratchy, sore throat, a relentless fever, a pounding head and a nasty cough – these symptoms all scream upper respiratory illness. But which one?
Many of the viruses that cause upper respiratory infections such as influenza A or B and the virus that causes COVID-19 all employ similar tactics. They target the same areas in your body – primarily the upper and lower airways – and this shared battleground triggers a similar response from your immune system. Overlapping symptoms – fever, cough, fatigue, aches and pains – make it difficult to determine what may be the underlying cause.
Now, at-home rapid tests can simultaneously determine whether someone has COVID-19 or the flu. Thanks in part to the National Institutes of Health’s Rapid Acceleration of Diagnostics, or RADx, program, the Food and Drug Administration has provided emergency use authorization for seven at-home rapid tests that can distinguish between COVID-19, influenza A and influenza B.
Our team in Atlanta – composed of biomedical engineers, clinicians and researchers at Emory University, Children’s Healthcare of Atlanta and Georgia Institute of Technology – is part of the RADx Test Verification Core. We closely collaborate with other institutions and agencies to determine whether and how well COVID-19 and influenza diagnostics work, effectively testing the tests. Our center has worked with almost every COVID and flu diagnostic on the market, and our data helped inform the instructions you might see in many of the home test kits on the market.
While no test is perfect, to now be able to test for certain viruses at home when symptoms begin can help patients and their doctors come up with appropriate care plans sooner.
A new era of at-home tests
Traditionally, identifying the virus causing upper respiratory illness symptoms required going to a clinic or hospital for a trained medical professional to collect a nasopharyngeal sample. This involves inserting a long, fiber-tipped swab that looks like a skinny Q-tip into one of your nostrils and all the way to the back of your nose and throat to collect virus-containing secretions. The sample is then typically sent to a lab for analysis, which could take hours to days for results.
Thanks to the COVID-19 pandemic, the possibility of using over-the-counter tests to diagnose respiratory illnesses at home became a reality. These tests used a much gentler and less invasive nasal swab and could also be done by anyone, anytime and in their own home. However, these tests were designed to diagnose only COVID-19 and could not distinguish between other types of illnesses.
Since then, researchers have developed over-the-counter multiplex tests that can screen for more than one respiratory infection at once. In 2023, Pfizer’s Lucira test became the first at-home diagnostic test for both COVID-19 and influenza to gain emergency use authorization.
What are multiplex rapid tests?
There are two primary forms of at-home COVID-19 and COVID-19/flu combination tests: molecular tests such as PCR that detect genetic material from the virus, and antigen tests – commonly referred to as rapid tests – that detect proteins called antigens from the virus.
The majority of over-the-counter COVID-19 and COVID-19/flu tests on the market are antigen tests. They detect the presence of antigens in your nasal secretions that act as a biological signature for a specific virus. If viral antigens are present, that means you’re likely infected. https://www.youtube.com/embed/s45GMoZaHFE?wmode=transparent&start=0 Respiratory illnesses such as flu, COVID-19 and RSV can be hard to tell apart.
To detect these antigens, rapid tests have paper-like strips coated with specially engineered antibodies that function like a molecular Velcro, sticking only to a specific antigen. Scientists design and manufacture specialized strips to recognize specific viral antigens, like those belonging to influenza A, influenza B or the virus that causes COVID-19.
The antibodies for these viral targets are placed on the strip, and when someone’s nasal sample has viral proteins that are applied to the test strip, a line will appear for that virus in particular.
Advancing rapid antigen tests
Like all technologies, rapid antigen tests have limitations.
Compared with lab-based PCR tests that can detect the presence of small amounts of pathogen by amplifying them, antigen tests are typically less sensitive than PCR and could miss an infection in some cases.
All at-home COVID-19 and COVID-19/flu antigen tests are authorized for repeat use. This means if someone is experiencing symptoms – or has been exposed to someone with COVID-19 but is not experiencing symptoms – and has a negative result for their first test, they should retest 48 hours later.
Another limitation to rapid antigen tests is that currently they are designed to test only for COVID-19, influenza A and influenza B. Currently available over-the-counter tests aren’t able to detect illnesses from pathogens that look like these viruses and cause similar symptoms, such as adenovirus or strep.
Because multiplex texts can detect several different viruses, they can also produce findings that are more complex to interpret than tests for single viruses. This may increase the risk of a patient incorrectly interpreting their results, misreading one infection for another.
Researchers are actively developing even more sophisticated tests that are more sensitive and can simultaneously screen for a wider range of viruses or even bacterial infections. Scientists are also examining the potential of using saliva samples in tests for bacterial or viral infections.
Additionally, scientists are exploring integrating multiplex tests with smartphones for rapid at-home diagnosis and reporting to health care providers. This may increase the accessibility of these tests for people with vision impairment, low dexterity or other challenges with conducting and interpreting at-home tests.
Faster and more accurate diagnoses lead to more targeted and effective treatment plans, potentially reducing unnecessary antibiotic use and improving patient outcomes. The ability to rapidly identify and track outbreaks can also empower public health officials to better mitigate the spread of infectious diseases.

5 Summer Safety Risks Homeowners Often Overlook When Hosting
Summer is the perfect season for gathering outdoors with friends and family, but if you’re a homeowner planning to host barbecues, pool parties or holiday celebrations this year, it’s important to consider the potential safety and liability risks that may be affecting your own backyard. Set your summer up for success by paying special attention to these five often-overlooked seasonal safety risks.
5 Summer Safety Risks Homeowners Often Overlook When Hosting
(Feature Impact) Summer is the perfect season for gathering outdoors with friends and family, but if you’re a homeowner planning to host barbecues, pool parties or holiday celebrations this year, it’s important to consider the potential safety and liability risks that may be affecting your own backyard. A little advance planning can help you ensure that your guests enjoy safe, healthy experiences at your home and leave with only happy memories.
According to the U.S. Consumer Product Safety Commission, thousands of injuries each year are linked to fireworks, grills and swimming pools. While most summer gatherings end without incident, Mercury Insurance is encouraging homeowners to remember that smart preparation can help you avoid unfortunate accidents and costly damage.
“A few simple safety checks can help homeowners create a safer environment for everyone while protecting the property they’ve worked hard to build,” said Larry Anderson, underwriting operations director at Mercury Insurance.
Set your summer up for success by paying special attention to these five often-overlooked seasonal safety risks.
Guest Injuries and Liability Risks
Since summer gatherings naturally increase foot traffic around a property, it should be safe to walk around. Uneven walkways, loose decking, poor lighting and pet-related incidents can all lead to injuries that homeowners may not anticipate.
Before hosting events, audit your property to repair trip hazards and ensure walkways and outdoor gathering areas are well-lit. If you have pets that may become stressed around large groups, secure them before guests arrive. Since unforeseen events can still occur despite your best efforts, review your liability coverage to understand available protections.
Unsupervised Pool Areas
Swimming pools can provide endless summer fun, but they also present one of the most serious safety risks around the home. Drowning remains a leading cause of accidental death for young children, making active supervision essential whenever children are near water.
If your backyard includes a pool, ensure that gates and barriers are functioning properly, keep rescue equipment nearby and consider pool alarms and self-closing gates for additional protection. Most importantly, never leave children unattended around water.
Backyard Grill Fires
Grilling is a summer tradition, but outdoor cooking equipment can quickly become a fire hazard if used improperly. Placing your grill too close to flammable objects, letting grease build up and leaving the grill unattended can all increase the risk of property damage.
Start by making sure your grill is set up at least 10 feet away from homes, fences and overhangs before you fire it up. Clean grease trays regularly, never leave a grill unattended while cooking and keep a fire extinguisher accessible during outdoor cooking.
Fireworks Too Close to Homes and Landscaping
Fireworks-related fires increase significantly during summer, particularly in dry climates where even one stray spark can ignite vegetation or nearby structures.
The safest option, when possible, is to attend professional displays rather than hosting your own. However, if you’re planning on lighting up your skies this summer, follow all local laws and restrictions regarding fireworks and keep your launch site well away from homes, vehicles and dry landscaping. Have a water source readily available when using legal consumer fireworks.
Outdoor Electrical Hazards
Extension cords, decorative lighting, outdoor speakers and fans often receive extra use during summer gatherings. Damaged cords or overloaded outlets can create shock and fire hazards. As you set up your summer entertainment systems, check your equipment to be sure it’s rated for outdoor use. Keep electrical connections away from pools and water features, avoid overloading electrical outlets and take a few extra minutes before each gathering to inspect outdoor cords for wear and damage.
“Most homeowners focus on making their gatherings enjoyable, but safety should be part of the preparation process,” Anderson said. “Taking a few minutes to identify potential hazards before guests arrive can help prevent accidents and allow everyone to focus on enjoying the season.”

The big summer trip is getting harder to pull off. What families are doing instead.
Big Summer Trip: Ask most Americans about their favorite summer memory, and water shows up somewhere — a lake at dusk, a boat rocking gently, quiet mornings with nowhere else to be.
The big summer trip is getting harder to pull off. What families are doing instead.
(Tiffany Miller) Ask most Americans about their favorite summer memory, and water shows up somewhere — a lake at dusk, a boat rocking gently, quiet mornings with nowhere else to be. For a lot of them, that feeling has been easier to remember than recreate.
As travel costs climb and traditional vacations feel increasingly complicated, the appeal of something closer to home has grown. Each year, 85 million Americans find it on the water, according to the National Marine Manufacturers Association (NMMA).
Part of boating’s appeal is rooted in nostalgia and connection. Many people are drawn to the kinds of unplugged experiences tied to childhood — time outdoors, shared adventures and uninterrupted moments together. According to a Discover Boating survey, 85% of current boat owners say their fondest childhood memories involved being on the water, with nearly half recalling those experiences before age 13.
The costs look different when stacked against a traditional vacation. According to NMMA, a week at an all-inclusive resort for a family of four runs around $5,000 to $8,000. Boat rentals run around $75 per hour, entry-level boat financing costs a few hundred dollars a month and boat club memberships offer access to multiple boats for a monthly fee, typically $150 to $375 after a one-time initiation fee. Many families are discovering that boating can offer multiple smaller vacations throughout the summer at a comparable cost.
Those lower-commitment options are more than just a budgeting tool — they are a first step into the lifestyle. According to the survey, 45% of prospective boat buyers expressed interest in renting or chartering before committing to a purchase, while interest in boat clubs and fractional ownership also remained high. The survey further found that 49% plan to own within two years, and 46% are focused on boats priced under $50,000.
For Americans deciding how to spend their time this summer, that flexibility may be part of boating’s growing appeal. It offers something many vacations promise but do not always deliver: the ability to truly disconnect and be present — not just once a year, but repeatedly throughout the season.
The pull toward the water may be deeper than nostalgia. Research shows there’s a connection between water and well-being — the sight and sound of water can help people feel calmer, lower stress and support overall wellness. The concept of “Blue Mind” describes the mild meditative state associated with being near, in, on or under water. For families looking to unplug, boating offers a way to step away from screens, slow down and recharge.
Methodology
The quantitative survey was fielded Aug. 22, 2025 through Sept. 12, 2025. It included 500 boat owners and 500 prospective owners. Boat owners are defined as those who own (or used to own) a boat and consider their primary vessel a motorized/power boat or sailboat. Prospective owners are defined as 50% or more likely to purchase a motorized/power boat or sailboat in the future and not a current or lapsed owner. Note: All insights collected reflect opinions of surveyed boat owners and prospective owners only.
